Sirgartan Therapeutics is an early-stage drug development company established in 2020 with the vision to transform the treatment paradigm for OCD (obsessive compulsive disorder) and deliver life-changing medicines for patients with OCD and other related neuropsychiatric disorders. The company’s mission is to identify and develop innovative single or combination treatments for OCD in conjunction with the world-leading neurological research resource provided by the University of Cambridge, UK.


Sirgartan is also investigating other potential neurological disorder therapies in conjunction with the Cambridge Consulting Network (CCN). These will constitute the pipeline for further studies into mental illnesses, including eating disorders, body dysmorphia and a range of other less recognised, but highly debilitating conditions.


Investment obtained through initial seed-funding has enabled early- stage pre-clinical studies to be carried out by the University of Cambridge. These studies have shown very encouraging results, much to the satisfaction of Professor Trevor Robbins, Chief Scientific Advisor to Sirgartan. This has led to the recent submission of a patent application for the identified therapy and its method of action.


The organisation is now seeking further funding to enable progression into clinical studies in 2023. Please contact us at investors@sigartan.com should you or your organisation have an interest in investing in this opportunity..
